摘要
根据摩擦盘式制动装置中摩擦盘的实际几何尺寸,运用有限元多物理场方法,建立一个制动工况下三维瞬态热-结构耦合的计算模型,对制动装置工作过程中的温度场及应力场进行了数值模拟,揭示了制动过程中制动盘瞬态温度场/应力场的分布规律,为制动装置结构设计及选择摩擦副材提供重要理论依据。试验验证了设计的摩擦盘式定向制动装置结构紧凑,径向尺寸小,制动性能可靠。
A computational model of three-dimensional under braking condition was established, using finite transient thermal and element -multiphysics construction coupling method upon actual geometry of friction disc in braking device. Thermal field and stress field of friction disc in working condition were simulated, from which distribution rules of transient thermal field and stress field were revealed. It can be a theoretical reference for braking device design and friction components material choice. The designed friction disc type braking device was validated in test with merits of compact design, small radial dimension and reliable braking ability.
